Daniel Lieberman in Edge:

DanI've been thinking a lot about the concept of whether or not human evolution is a story of brains over brawn. I study the evolution of the human body and how and why the human body is the way it is, and I've worked a lot on both ends of the body. I'm very interested in feet and barefoot running and how our feet function, but I've also written and thought a lot about how and why our heads are the way they are. The more I study feet and heads, the more I realize that what's in the middle also matters, and that we have this very strange idea —it goes back to mythology—that human evolution is primarily a story about brains, about intelligence, about technology triumphing over brawn.

Another good example of this would be the Piltdown hoax. The Piltdown forgery was a fossil that was discovered in the early 1900s, in a pit in southern England. This fossil consisted of a modern human skull that had been stained and made to look really old, and an orangutan jaw whose teeth had been filed it down and broken up, all thrown into a pit with a bunch of fake stone tools. It was exactly what Edwardian scientists were looking for, because it was an ape-like face with a big human brain, and also it evolved in England, so it proved that humans evolved in England, which of course made sense to any Victorian or Edwardian. It also fit with the prevailing idea at the time of Elliot Smith, that brains led the way in human evolution because, if you think about what makes us so different from other creatures, people always thought it's our brains. We have these big, enormous, large, fantastic brains that enable us to invent railways and income tax and insurance companies and all those other wonderful inventions that made the Industrial Revolution work.
